Figure 3: A diagram showing the structures of the different nitrogenous bases. When we first studied the structure of DNA, one of the very first things that we learned is its characteristic double-stranded helical shape. Although the composition of RNA is very similar to that of DNA, it gene...
Electron dense bodies, osmophilic granules along with ribosomes (70S), circular DNA, RNA and soluble enzymes of Calvin cycles are also present in the matrix of the stroma. Chloroplasts thus have three different membranes, the outer, the inner and the thylakoid membrane. The thylakoid membran...
They are the smallest membrane-bound organelles which comprise RNA and protein. They are the sites for protein synthesis, hence, also referred to as the protein factories of the cell.

Parts of a Phylogenetic Tree Phylogenetic Tree Diagram Lesson Summary Register to view this lesson Are you a student or a teacher? FAQ What are the different types of phylogenetic trees? The two main types of phylogenetic trees are cladograms and phylograms. Cladograms do not have scaled br...
pathogenic at the RNA level through splicing alterations, and these mutations are often located in the splicing donor, acceptor, and intronic regions. Consequently, splicing alterations have also been considered for the pathogenicity evaluation of mutations [18,19]. However, in clinical practice of ...
We present an online platform, Allen Brain Cell Atlas, to visualize the mouse whole-brain cell-type atlas along with the single-cell RNA-sequencing and MERFISH datasets. We systematically analysed the neuronal and non-neuronal cell types across the brain and identified a high degree of ...
Due to the dual factors of tumor immune tolerance and autoimmune reaction, it is urgent to understand the immune status of MG with thymoma. In this study, RNA sequencing data were obtained from the TCGA and GEO cohorts to identify differentially expressed messenger RNAs and infiltrated immune ...
SSAM consists of 4 major steps (Fig.1), namely (1) mRNA signal estimation and downsampling; (2) computation of cell-type signatures; (3) generation of a cell-type map; and (4) identification of tissue domains. Fig. 1: Schematic diagram of the SSAM computational workflow for cell type ...

Any change in the DNA - any mutation - will change the RNA sequence and most likely also change the resulting protein. The reading frame of a gene is how the nucleotides are partitioned into groups of three; each RNA sequence has three possible reading frames (each DNA sequence has six -...
